6.3 Maintenance Commands

The following commands can be used for maintenance when an EPAP-related feature is on.

Refer to Commands User's Guide for complete descriptions of the commands, including parameters, valid parameter values, rules for using the commands, and output examples.

Table 6-3 Maintenance Commands

Command	Description
rept-stat-sys	Reports the status of system entities, including cards. The output includes the number of Service Module cards that are in service (IS-NR) and how many are in another state (IS-ANR, OOS-MT, OOS-MT-DSBLD).
rept-stat-sccp	Reports operating status of services and subsystems, CPU usage, and Service Module card status. When the loc parameter is specified, the command displays detailed card traffic statistics, including cards that are denied SCCP service. See the section in this manual that describes the use of the `rept-stat-sccp` command.
rept-stat-mps	Displays the overall status of the EPAP application running on the MPS (multi-purpose server). Command output for the various reports of this command include overall MPS alarm status and card status, and status for a specific Service Module card when a feature is on.
rept-stat-trbl	Includes a summary of any trouble notifications (UAMs) for local subsystems, cards, and linksets. The severity of each alarm is indicated in the output report.
rept-stat-alm	Displays the alarm counts and totals for local subsystems and Service Module card/EPAP IP links.
rept-stat-db	Displays the status information for the EAGLE databases. This includes the level information for each Service Module card, and for the active and standby EPAP RTDB. The command reports database exception status such as corrupted, incoherent, or inconsistent, as well as providing the birth dates and levels. It shows the status of each PDB and RTDB when an EPAP-related feature is enabled.
rtrv-tbl capacity	Retrieves table use capacity summary information. For each table listed, the number of table entry elements in use and the total allowed number of table elements is presented, along with a percent (%) full value. Information is shown for some tables only if the feature that uses the table is enabled.
inh-card/alw-card	The `inh-card` command is used to change the operating state of the card from In-Service Normal (IS-NR) to Out-of-Service Maintenance-Disabled (OOS-MT-DSBLD). A craftsperson then can test the card or physically remove it from the shelf. The `alw-card` command is used to change the card from OOS-MT-DSBLD (Out-of-Service Maintenance-Disabled) to IS-NR (In-Service Normal) if card loading is successful.
inh-alm/unhb-alm	Used to allow and inhibit reporting of alarms for a given device, including the Service Module card ports. The commands allow both Port A and Port B to be specified. Inhibited alarms will not generate UAMs or cause alarm indicators to be turned on. All `rept-stat-xxx` commands continue to display the alarms with an indication that the device has its alarms inhibited.
rtrv-data-rtdb	Retrieves Entity data, DN data, IMEI data, IMSI data, TN data, NPANXX data, and LRN data from the RTDB on an active Service Module card. If the loc parameter is specified and the target card is an active Service Module card, the RTDB data is retrieved from that card. If the loc parameter is not specified, the RTDB data is retrieved on the active Service Module card that has the lowest IMT address. The RTDB status on the active Service Module card can be coherent or incoherent.

6.3.1 rept-stat-sccp

The rept-stat-sccp command provides statistics for Service Module cards and for the services that execute on the cards. The statistics can be displayed for all Service Module cards or for a specified card.

Refer to Commands User's Guide for a description of the rept-stat-sccp command, including parameter names, valid parameter values, rules for using the command, and output examples.

The rept-stat-sccp command reports current MNP statistics. An MSU is considered to be a G-Port MSU after service selection.

6.4 Debug Commands

Commands User's Guide contains descriptions of debug commands that can be used in assessing and modifying system status and operation. Most debug commands are used only under the direction of Oracle support personnel. Refer to Commands User's Guide for a complete description of the debug commands, including the ent-trace command.

G-Port uses the ent-trace command to provide a trap-and-trace function for MSUs on the Service Module cards. G-Port also includes a trigger so that the user can trigger on DN and IMSI.

The user can create an MSU trigger on the Service Module card on one or more criteria (both old and new) defined in the following using the ent-tracecommand. When multiple trigger criteria are entered, the MSU is trapped when any one of the criteria is satisfied.

Caution:

As with other debug commands, the ent-trace command can cause OAM to reset if too many MSUs are trapped.

RN or SP address (Entity ID) - Use this new criterion to trap messages immediately after performing the RTDB lookup. If the RN or SP obtained from the database lookup matches the Entity ID provisioned in the command, the message is trapped. This parameter supports a variable number of hexadecimal digits from 1 to 15 digits, and the Entity ID specified must be the one stored in the RTDB.
E.164 MSISDN number (DN) – Use this criterion to trap messages immediately before performing a G-Port search based on the MSISDN numbers defined in the RTDB. This parameter accepts a range of digits, from 5 to 15. The number specified must be an International E.164 number (MSISDN or Entity Number).
Global Title digits (GT) – Use this criterion to trap messages based on CdPA Global Title Address (either MSISDN (+ST) number or RN + MSISDN (+ST)) present in the SCCP part of the message.
Origination point code SSPI/SSPN) – Use this criterion to trap messages based on CgPASPC present in the SCCP part of the message. If no point code is present in the CgPA SPC, the criteria is matched with the OPC present in the MTP part of the message.

A trace must be set on all Service Module cards; specify card=sccp-all. Use a repetition parameter (rep) to control the number of MSUs that are trapped.

MSUs that satisfy any trigger criteria are trapped on the Service Module cards, are forwarded to OAM, and are displayed. Refer to Commands User's Guide for a complete description of the ent-trace command, including parameters, valid parameter values, rules for using the command, and output examples.

6.5 Status Reporting and Problem Identification

EAGLE commands can be used to obtain status and statistics for the EAGLE system, the EPAP systems, system devices including Service Module cards, EPAP-related features, local subsystems, and SCCP services.

Refer to Commands User's Guide for complete descriptions of the commands, including parameters and valid values, rules for using the commands correctly, and output examples.

6.5.1 EPAP Status and Alarm Reporting

Because EPAP has no direct means of accepting user input or displaying output messages on EAGLE terminals, EPAP maintenance, measurements, and status information are routed through a Service Module card. EPAP sends two types of messages to the Service Module card: EPAP Maintenance Blocks and DSM Status Requests and DSM Status Messages. Each message type is discussed in the following sections.

EPAP Maintenance Blocks

The EPAP forwards all status and error messages to the Service Module cards in maintenance blocks. Maintenance blocks are asynchronously sent whenever the EPAP has something to report. The status information that is displayed when a rept-stat-mps command is issued includes information that came from the maintenance blocks.

The active EPAP generates and sends maintenance blocks to the primary Service Module card. One maintenance block is sent as soon as the IP link is established between the active EPAP and the primary Service Module card. Additional maintenance blocks are sent whenever the EPAP needs to report any change in status or error conditions. The information returned in maintenance blocks is included in the output of the rept-stat-mps and rept-stat-sccp commands.

The EPAP sends maintenance blocks that contain at least the following information:

Status of EPAP A - actual states are active, standby, and down (inoperative). Maintenance blocks include a field for this information so that it can be available for the output of the rept-stat-mps command.
Status of EPAP B - actual states are active, standby, and down (inoperative). Maintenance blocks include a field for this information so that it can be available for the output of the rept-stat-mps command.
Identification of Active EPAP - a field to identify the active EPAP.
Congestion Indicator - an indicator showing provisioning link congestion. The link between the EPAPs and the external source of provisioning data can become congested in high-provisioning traffic situations. When this occurs and subsequently as the congestion clears, the EPAP sends maintenance blocks to the Service Module card.
Alarm Conditions - an error code field. If the EPAP needs to report an alarm condition, it puts an appropriate UAM identifier in this field.
Current MPS Database Size - a field indicating the current RTDB size. The Service Module card uses this information to calculate the percentage of memory used by the RTDB.

DSM Status Requests and DSM Status Messages

When the EPAP needs to know the status of a Service Module card, the EPAP sends a DSM Status Request to all Service Module cards, and each Service Module card returns its status to the EPAP.

Service Module cards send a DSM Status Message to the EPAP when any the following events occur in the Service Module card:

The Service Module card is booted.
The Service Module card receives a DSM Status Request message from the EPAP.
The Service Module card determines that it needs to download the entire RTDB; for example, the Service Module card determines that the RTDB needs to be downloaded because it is totally corrupted, or a user requests that the RTDB be reloaded. The Service Module card sends a Full Download Request message to the EPAP
The Service Module card starts receiving RTDB downloads or updates. When a Service Module card starts downloading the RTDB or accepting updates, the Service Module card sends a DSM Status Message informing the EPAP of the first record received. This helps the EPAP keep track of downloads in progress.

The DSM Status Message provides the following information to the EPAP:

DSM Memory Size. When the Service Module card is initialized, it determines the amount of memory present. The EPAP uses the value to determine if the Service Module card has enough memory to hold the RTDB.
Load Mode Status. This indicator indicates whether or not a sufficient number of the IS-NR (In-Service Normal) LIMs have access to SCCP services.

6.5.2 Hourly Maintenance Report

The Hourly Maintenance Report, generated automatically, includes the alarm totals of the INP/AINPQ subsystem and Service Module card /EPAP IP links. A sample follows.
